Answer:
x = 11
Step-by-step explanation:
The angles in a square are right , that is 90°
The diagonals bisect the angles , then
6x - 21 = 45 ( add 21 to both sides )
6x = 66 ( divide both sides by 6 )
x = 11

Emily says she can prove the Pythagorean Theorem using the following diagram. She explains that she can divide the squares on the two shorter sides into grids with equal-sized grid squares. She says she can then rearrange the grid squares to cover the area of the square on the hypotenuse, which proves that the sum of the squares on the two shorter sides equals the square on the hypotenuse. A 3 by 3 square, a 4 by 4 square, and a 5 by 5 square, put together to form a right triangle with legs 3 and 4 and hypotenuse 5. Is this a valid geometrical proof that a2 + b2 = c2 for all right triangles? Yes, because there are 9 grid squares on one side, 16 grid squares on the other side, and 25 grid squares on the hypotenuse, and 9 + 16 = 25. Yes, because it shows that you can rearrange the squares on the shorter sides to fill up the area of the square on the larger side. No, because a proof needs to have equations in order to be valid. No, because this proof only works when you can draw grids on the squares. It does not work for all right triangles.

A farmer wants to fence an area of 6 million square feet in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle. Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence. Let F represent the length of fencing in feet. Write an equation that represents F in terms of the variable x.
Answers
If the rectangular field has notional sides X and y then it has area
A(x) =xy { =6•10^6 sq ft }
The length of fencing required, if
x
is the letter that was arbitrarily assigned to the side to which the dividing fence runs parallel, is:l (x) = 3x +2y
It matters not that the farmer wishes to divide the area into 2 exact smaller areas.
Assuming the cost of the fencing is proportional to the length of fencing required, then
C(x)=a L (x)
To optimise cost, using the Lagrange Multiplier
λ
, with the area constraint :
So the farmer minimises the cost by fencing-off in the ratio 2:3, either-way
The relationship between variable F and x is 2x + 12000000/x
Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence.
Let F represent the length of fencing in feet.
Area of fencing = 6000000 ft²
Area of fencing = x * (y + y) = x * 2y
Area of fencing = 2xy
6000000=2xy
xy = 3000000
y = 3000000/x
The perimeter is:
F = x + y + y + x + y + y
F = 2x + 4y
F = 2x + 4(3000000/x)
F = 2x + 12000000/x
Therefore the relationship between variable F and x is 2x + 12000000/x

Step-by-step explanation:
The expected value equation is the probability of something happening multiplied by the amount of times it happens. In this case you have four equal sized sections, so you have a one in four chance to land in any of these sections. A, B, D, and F represent the four for this one in four chance.

A new car is purchased for 22300 dollars. The value of the car depreciates at 10.25% per year. What will the value of the car be, to the nearest cent, after 6 years?
Answers
Answer:
$11654 approx
Step-by-step explanation:
Given data
Principal amount = 22300 dollars
Rate= 10.25%
time= 6 years
The expression for the decrease is given as
A=P(1-r)^t-----------Note the negative sign is because of the decrease
substitute
A= 22300(1-0.1025)^6
A=22300(0.8975)^6
A=22300*0.5226
A=$11653.98
Hence the new value is $11654 approx

Distribute the 2 to the 5x and -5.
10x - 10 = 6x + 50
Add 10 to both sides, and subtract 6x from both sides.
4x = 60
Divide both sides by 4.
x = 15
5y + 5 = 7y - 9
Subtract 5 from both sides, and 7y from both sides.
-2y = -14

128= 4^2x times 2^x
What is x?
Answers
Answer:
x=7/5
Step-by-step explanation:
We can write it in exponential form
128= 2^2*2x * 2^x
2^4x+x=5x
2^5x=128
2^5x=2^7
5x=7
x=7/5
The value of x in the equation given is
[tex] \frac{7}{5} [/tex]
To solve :
[tex]128 = {4}^{2x} \times {2}^{x} [/tex]
Change all values to have the same root :
[tex] {2}^{7} = {2}^{2(2x)} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{4x} \times {2}^{x} [/tex]
[tex] {2}^{7} = {2}^{(4x + x)} [/tex]
[tex] {2}^{7} = {2}^{5x} [/tex]
The roots cancel out
[tex] 7 = 5x[/tex]
Divide both sides by 5
[tex]x = \frac{7}{5} [/tex]

The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.
We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get
